Holders and replacement trays for disposable pipette tips; designed and packaged to facilitate the reuse of pipette tip boxes to reduce the overall amount of plastic waste; available in a variety of configurations and with and without pipette tips.

Pipette tip racks and inserts are available in various styles to accommodate different kinds of pipette tips.

Pipette tips are usually sold unracked, racked, or in a configuration that makes them easy to reload or refill. Many reload systems are stackable to save bench space and storage space, and to maintain pipette tip sterility. Outer sleeves on sterile pipette tips protect them from contamination during refill.

Some racks are numbered, and the tips may be lot-controlled for traceability. Other racks are vented so that tips can be autoclaved. Empty racks are also available to help with manual filling.

Pipette tip racks and inserts are available for:

• Filtered and unfiltered universal pipette tips
• Filtered and unfiltered pipette-specific tips
• Filtered and unfiltered specialty pipette tips
